Improvement in evapoeatoes foe soeghum and othee sibups



@eine faire @aient @frn SOLOMON MCWORTER, OF BARRY, ILLINOIS. Letters Patent No. 70,4511, dated November 5, 1867.

IMPROVEMENT IN -EVAPORATORS FOR SORGHUM vAND OTHER SIRUPSL TO ALL WHOM ITMAY CONCERNE f Be it known that I, SOLOMON MCWORTER, of Barry, in the county of Pike, and State of Illinois, have invented a new and useful Improvementin Evaporators for Reducing Sorghum Aand other -like Sirups; and I do hereby declare that the following isa full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. I

This invention relates to the combination of a steam-boiler and evaporating-pan in such a manner that the heat -from the steam-boiler is imparted to the evaporating-p=m without any danger of scorching the sirup.

To enable those skilled in the art to make and use my improved evaporator, I will proceed to describe its construction and operation. Y

'Figure 1 of the drawings is a sectional eleva-tion of the improved boiler and evaporator.

Figure 2 is a plan of it. 4

There may be one or more of the evaporating-pans A, it being customary to usc for the evaporation of saccharine sirups a primary, secondary, and a finishing-pan. However-many of these pans may be used, they.

will be placed over a steam-boiler, B, which is heated from the furnace C, the boiler being provided witlrretrnilucs Cl and smoke-stack C2. I propose to ill the boiler by means oflhydrostatie pressure, using for this purpose a pipe, D, the lower end of which is connected with the lboiler, and the upper end is to be in open communication with a reservoir not shown. This arrangement will obviate the necessity of forcing-pumps, which would be impracticable for this application, and answer evcry'purpose, as the pressure required is quite low. It is desirable to have the bottom ofthe pan Aat, and in order to give this form of top for the boiler B sniecn't'strength, I s'ti'en it, by means ofthe transverse ribs a, shown by dotted lines in fig. 2. The faucet a is used to draw oil' the finished Sirup from the pan A.

'Having described my invention, what I claim is- 1. The combination and arrangement of the evaporating-pan A and the steam-boiler B, substantially as described and set forth.

v2. I claim the combination of the pipe D with the boiler B, as and for the purpose set forth.

3. I claimth'e employment ofthe stiffening-ribs a in combination with the flat crown-sheet of the boiler, as

described and set forth.
